OIL-GAS BURNER.

Specification of Letters Patent.

vention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in oil gas burners.

One object of the invention is to improve the construction of the burnershown in United States Patent, No. 956,114, granted to me April 26,1910, whereby the eiiiciency or heating capacity of the same is greatlyincreased, and the oil feeding and vaporizing mechanism improved.

With this and other objects in view, the invention consists of certainnovel features of construction,combination and arrange ment of partswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings :F igure 1 is a side view of my improvedburner; Fig. 2 is a top plan view; Fig. 3 is a central vertical sectionof the same; Fig. 4C is a side view of the inner oil deflecting cone;Fig. 5 is a central vertical sectional view of the outer deflectingcone; Fig. 6 is a similar view of the flame spreader removed from theburner; Fig. 7 is a plan view of a double l burn er.

Iuthe ,cmbodiment of the invention I pro vide an inner base member 1which is preferably in the form" of a circular bowl having ,its sidewalls preferably inclined inwardly toward the lower end. of the bowl asshown. In the bottom 2 of the bowl is formed a centrally disposed draftopening 3. In the bottom of the bowl around the opening 3 is formed anannular drip .or

drain channel 41 adapted to catch the over-,

flow oil. The base 1 serves to confine a part of the heat of the burnerwhich vapor izes the .oil and causes the same to mix with the air andthus form a highly combustible and economical gas. I

Arranged in the base and adapted to be engaged with the bottom 2 overthe opening 3 is an inner oil deflecting cone 5' havlng on itslower-edge an annular flange 6 and in its sides a series of verticallydis-' posed elongated air passages 7. A ound the side and top edges ofthe passages 7 are termed outwardly projecting flanges S. The spacesbetween the side thinges 8 form inclined grooves or channels in theupper end of the cone 5 is formed a threaded. feed opening with which isengaged the threaded end of the oil feed pipe 10, said pipe passing upthrough the opening 2 in the bottom and through the come as shown.

Arranged over the inner cone is an outer cone 11 said outer cone havingon its inner side a series of spacing ribs 12 which are adapted toengage the grooves 9'botween the flanges 8 on the inner cone therebyspacing said cones the proper distance apart. In the sides of the cone11 between the ribs 12 are formed passages 13 which register with thepassages 7 in the innercone. 'The passages 13 are divided centrally bylongi tudinal ribs 14; which project inwardly to a slight extent asshown. \Vith the upper end of the outer cone 11 is engaged a flamespreader 15 which is preferably in the form of a concaved or saucershaped circular plate. The spreader plate 15 is of less diameter thanthebase 1 and is disposed immediately above the upper end of the same asshown. By thus arranging the spreader the flame will be deflected anddirected against the sides of the fire box of the stove in which theburner is arranged.

In Fig. 7 of the drawing is shown a double arrangement of burner adaptedparticularly for use in fire boxes'of cooking stoves. In this form ofthe device two small burners are secured to a rectangular base plate 16in such position that one of the burners will be below each of theopenings in the to a of the stove over the fire box, when the base plateit) rests on the grate of the box.

In the operation ol the burner the oit is discharged from the feed pipebetween the fit upper portions'of the two cones and flows downwardly inthe grooves or-channels 9 in the inner cone 5 and around the ribs andflanges on said-cones and is vaporized by Contact with these parts whenthe same become heated. The flame from the oil and gas formedbyvaporized oil and air burns through the r passages 13 in the outer coneand blazesup out of the upper end of the base. The flame is deflectedwhen leaving the base by the spreader 15 as hereinbefore described andthe heating capacity of the burner thus greatly increased.

13y arrangil'ig the oil feed pipe as herein shown and described thedischarge end of the same is not exposed to the flame and therefore willnot become carbonized by the of this invention as defined in theappended claims.

l-Iavin g thus described my invention, What I claim is:

1. In an oil gas burner a bowl shaped base having in its bottom acentral draft opening, and an annular groove, an inner burner sectionarranged in said bowl over the opening therein, said inner sectionhaving therein a series of openings and a series of oil feeding grooves,an oil supply pipe arranged in and opening through said inner section,an outer section having formed therein a series of openings adapted toco incide with the'openings in the inner sections, longitudinal dividingribs arranged in said openings in the outer section, and a series ofribs formed on the inner side of the outer section and adapted to engagethe oil feeding grooves in said inner section.

2. Tn an oil gas burner a bowl shaped base having in its bottom acentral draft opening, and an annular giwsove. an inner burner sectionarranged in said bowl over {the opening therein, said inner sectionhaving therein a series of openings and a series of oil feeding grooves.an oil supply pipe arranged in and opening through said inner section,an outer section having formed therein a series of openings adapted tocoincide with the openings in the inner section, longitudinal dividingribs arranged in said openings in the outer section, a series of ribsformed on the inner side of the cuter section and adapted to engage theoil feeding passages in the inner section and a concaved spreader platereinovably engaged with and supported on said outer cone.

In testimony .whereof I have hereunto set my hand in presence of twosubscribing Witnesses.
